FLASH_CR_SNB field has too many bits in stm32h503xx.h

[Jochen0x90h]

Hi!

I found a bug in stm32h503xx.h (version 2023)

The SNB field has too many bits:

#define FLASH_CR_SNB_Msk (0x7FUL << FLASH_CR_SNB_Pos)

Correct is only three according to the reference manual (8 pages of 8K flash), therefore it should be

#define FLASH_CR_SNB_Msk (0x07UL << FLASH_CR_SNB_Pos)

With kind regards,

Jochen
